pub struct LaunchTemplateInstanceMetadataOptions {

The metadata options for the instance. For more information, see Instance Metadata and User Data in the Amazon Elastic Compute Cloud User Guide.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

state: Option<LaunchTemplateInstanceMetadataOptionsState>

The state of the metadata option changes.

pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selection.

applied - The metadata options have been successfully applied on the instance.

http_tokens: Option<LaunchTemplateHttpTokensState>

The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

http_put_response_hop_limit: Option<i32>

The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

Default: 1

Possible values: Integers from 1 to 64

http_endpoint: Option<LaunchTemplateInstanceMetadataEndpointState>

This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.

If you specify a value of disabled, you will not be able to access your instance metadata.

http_protocol_ipv6: Option<LaunchTemplateInstanceMetadataProtocolIpv6>

Enables or disables the IPv6 endpoint for the instance metadata service.

Default: disabled

Implementations

impl LaunchTemplateInstanceMetadataOptions

pub fn state(&self) -> Option<&LaunchTemplateInstanceMetadataOptionsState>

The state of the metadata option changes.

pending - The metadata options are being updated and the instance is not ready to process metadata traffic with the new selection.

applied - The metadata options have been successfully applied on the instance.

pub fn http_tokens(&self) -> Option<&LaunchTemplateHttpTokensState>

The state of token usage for your instance metadata requests. If the parameter is not specified in the request, the default state is optional.

If the state is optional, you can choose to retrieve instance metadata with or without a signed token header on your request. If you retrieve the IAM role credentials without a token, the version 1.0 role credentials are returned. If you retrieve the IAM role credentials using a valid signed token, the version 2.0 role credentials are returned.

If the state is required, you must send a signed token header with any instance metadata retrieval requests. In this state, retrieving the IAM role credentials always returns the version 2.0 credentials; the version 1.0 credentials are not available.

pub fn http_put_response_hop_limit(&self) -> Option<i32>

The desired HTTP PUT response hop limit for instance metadata requests. The larger the number, the further instance metadata requests can travel.

Default: 1

Possible values: Integers from 1 to 64

pub fn http_endpoint(
    &self
) -> Option<&LaunchTemplateInstanceMetadataEndpointState>

This parameter enables or disables the HTTP metadata endpoint on your instances. If the parameter is not specified, the default state is enabled.

If you specify a value of disabled, you will not be able to access your instance metadata.

pub fn http_protocol_ipv6(
    &self
) -> Option<&LaunchTemplateInstanceMetadataProtocolIpv6>

Enables or disables the IPv6 endpoint for the instance metadata service.

Default: disabled
